Measures up to 3% CO2
2kHz alarm
Data logger

This hand-held CO2 alarm is an extremely small, light weight, battery operated precision instrument designed to warn the user when carbon dioxide concentrations reach dangerous levels.

The LED display shows the carbon dioxide concentration and time-weighted average (TWA) in real time while a series of LEDs instantly shows the user when CO2 levels are dangerous. In addition, a 2kHz alarm will sound until the user presses a button.

A built-in data logger also makes it the perfect choice for monitoring CO2 in a number of different applications and environments. And the sensor’s gold-plated infra-red waveguide and diffusion membrane filter provides reliability, accuracy and long-term stability.
